10x + 4x 3 – 4 Write the polynomial in standard form. Then name the polynomial based on its degree and number of terms.

weqwewe [10]

Guessing that the 3 was suppose to be an exponent.

The answer written in standard form is :
4x^3 + 10x - 4

This is called a cubic trinomial.

One positive number is the square of another positive number. their sum is 132. find the numbers.

Jet001 [13]

X +x²= 132
x +x²-132= 132-132
x²+x -132 = 0
(x-11) (x+12) = 0
x-11 = 0 X+12=0
x-11+11 = 0+11 X+12-12=0-12
x =11 x= -12

Check
x +x²= 132 x +x²= 132
-12 +-12²= 132 11 +11²= 132
-12 + 144 = 132 11+ 121=132
132= 132 132=132

Since the problem says positive the answer is (11,121)

What is the distance between the points (2,6) and (5,8)? Round to the

lidiya [134]

The distance between given points is 3.6 units.

Step-by-step explanation:

Given points are;

(2,6) and (5,8)

Here;

$x_1=2\\y_1=6\\x_2=5\\y_2=8$

Distance between two points is calculated by;

$Distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\\\Distance = \sqrt{(5-2)^2+(8-6)^2}\\\\Distance = \sqrt{(3)^2+(2)^2}\\\\Distance = \sqrt{(9+4)}\\\\Distance = \sqrt{13}\\\\Distance=3.6\ units$

The distance between given points is 3.6 units.
